DOOR KEY AT TACHMENT Filed Nov. 11, 1950 Patented Jan. 1%, i933 WILHELM KLQTZ, OF DUSSELDGBF, GERMANY EDGE-KEY ATTACI'IIIIENT Application filed November 11, 1930, Serial No. 494,910, and in Germany January 1, 1930.

I have filed applications in: Germany filed the 1st January 1930, France filed the lth July 1930, Belgium filed the 7th July 1930, Switzerland filed the l lth February d Door-key attachments for hotels and the like are usually made of wood or such like hard material and of a sufliciently large size to prevent the key from being carried away 10 in the pocket by mistake. The use of key attachments of this kind has many disadvantages, however, the most serious of which are the unavoidable damage to the painted wood of the doors and the disturbing noise when they hit against the door or any hard object.

The present invention consists of a key attachment in which the drawbacks above men tioned are absent.

According to the invention, the key attachments are provided with elastic buffer surfaces. These can be designed in such a way that the entire attachment is made of rubber only, or formed as a hollow rubber body. Alternatively it may take the form of a more or less hard core covered with a rubber coatmg.

The single figure of the annexed drawing is an elevation, partly in longitudinal section, of a preferred embodiment of the present invention.

The key attachment of the present invention consists entirely of rubber or like substance. The shape may be of any form that may be desired, but is illustrated as of spherical form, comprising a rubber ball 12 which can be left hollow or can be stuffed with a filling 13 of spongy rubber, cellular rubber (known also as sorbo) or scrap rubber or other like material. The spherical shape provides a hand grip. The eyelets 14; can be fixed in any way desired.

The rubber body can be marked by mould ing, stamping or otherwise indicating the number of the room as well as the name of the firm.

What I claim is Door-key attachment consisting of a hollow rubber ball having a stuffing of spongy rubber, sorbo or scrap rubber or similar elastic material, and an eyelet attached thereto.
